Abstract:

Polymer processing in modern industry is often not efficient from the point of view of energy and material consumption. This production system must be revised to pursue a circularity of products and materials. Recent developments in additive manufacturing technologies for polymers and polymer-based composites are enabling changes of production paradigm from “Design for Manufacturing” to “Manufacturing for Design”, providing new intriguing lightweight solutions. This paper summarizes the lesson learned from the RELIVE project “REcycling of pLastic wastes integrating extrusion and additIVE manufacturing techniques”, in terms of methodology and results.
